GE Aviation Bromont (GEAB) is currently developing ceramic matrix composites (CMCs) for engine**applications. These CMCs are made with silicon carbide (SiC) ceramic fiber embedded in a SiC matrix**material. The SiC ceramic fibers forming the yarns are highly stiff and brittle. During all yarn handling**operations (e.g., coating, spooling, etc.), yarns undergo a moderate level of damage. This damage accumulates**and has a detrimental effect on both part quality and yield. A recent collaboration between GEAB and**Polytechnique Montreal has resulted in the development of a modelling and testing approach to understand the**fiber damage mechanisms during yarn processing. As a continuation of this project, this present Engage Plus**proposal's objective is to develop and validate a modelling approach to understand the fiber damage evolution**during yarn processing. A parametric non-linear finite element model has been created in Abacus to represent**yarn handling situations. This model will now be used to compare different parameters' influence on friction**dissipated energy and damage. A small test rig using a moving yarn torture device running against a yarn fixed**between to load cells has been built. This rig will now be used to reproduce different damage creation**conditions. Test conditions will include yarn moving speed against the pulleys, rotation speed of the pulleys,**diameter and shape of the pulleys, and pulley material. With this project, we will develop validated modelling**approaches to understand fiber-fiber and fiber-surface friction interactions. GE Aviation Bromont will expand**its R&D efforts towards high performance composite applications in aircraft engines.

GE Aviation Bromont（GEAB）目前正在开发用于发动机 ** 应用的陶瓷基复合材料（CMC）。这些CMC由嵌入SiC基质 ** 材料中的碳化硅（SiC）陶瓷纤维制成。形成纱线的SiC陶瓷纤维是高度刚性和脆性的。在所有纱线处理 ** 操作期间（例如，涂布、卷绕等），纱线受到中等程度的损伤。这种损坏会累积 **，并对零件质量和产量产生不利影响。GEAB和 **Polytechnique Montreal最近合作开发了一种建模和测试方法，以了解纱线加工过程中的 ** 纤维损伤机制。作为该项目的延续，本Engage Plus** 提案的目标是开发和验证一种建模方法，以了解纱线加工过程中的纤维损伤演变 **。在Abacus中创建了一个参数化非线性有限元模型来表示 ** 纱线处理情况。该模型将用于比较不同参数对摩擦耗散能和损伤的影响。一个小型试验台使用移动纱线酷刑装置运行对纱线固定 ** 之间的负荷传感器已经建成。这个装备现在将被用来复制不同的伤害创造条件。测试条件将包括纱线相对于滑轮的移动速度、滑轮的旋转速度、** 滑轮的直径和形状以及滑轮材料。通过这个项目，我们将开发有效的建模方法来理解纤维与纤维和纤维表面摩擦的相互作用。GE Aviation Bromont将扩大 ** 其研发工作，将高性能复合材料应用于飞机发动机。
